“Combining the latest technology in digital power and advanced coreless energy transfer, the GB350 is an important component of the Powerbox Custom Power Solution toolbox,” said Tomas Isaksson, chief technology officer.
The GB350 buck converter module can operate safely when exposed to high radiation magnetic fields of 2 to 4Tesla. The GB350 delivers an output power of 350W and when higher power levels are required, it can be paralleled using an interleaving mode, thus reducing EMI.
Designed to guarantee a tightly regulated output voltage at any load-condition, the power unit is fully controlled by a digital processor that manages the complete power unit from switching parameters to output voltage characterisation.
To guarantee a high level of flexibility and the possibility to re-profile characteristics when equipment manufacturers upgrade new hardware or implement a software revision, the MCU can be programed with configuration files downloaded through the digital interface.
The standard platform delivers a nominal current of 50A and preset output voltages of 6.8, 3.3 or 1.6V. As part of the custom power solution toolbox, other output voltages are available on request.
With a switching frequency of 600kHz and its four phase interleave mode, the GB350 has a resultant output frequency of 2.4MHz. This is said to allow easier filtering and fast regulation response times. The unit also includes EMI shielding to lower radiated emission.
